EF1 tornado in Williamson County, Texas

A NWS storm survey team concluded a tornado touched down in the Gabriel's Overlook subdivision in Williamson County, roughly four miles northeast of Leander. The tornado snapped large tree limbs through its path length. The tornado also caused damage to two homes, with roof decking on the corner of one home removed, and over half the roof decking on the second home completely removed. Two large storage sheds were are also picked up and moved 20 yards. Peak winds were estimated at 95-100 mph, where the most significant damage occurred to the second house.

An upper level shortwave trough moved around the longwave low over the Four Corners region. This upper distubance interacted with a surface boundary moving northward as a warm front from South Texas into a very moist airmass. This combination led to thunderstorms that produced heavy rain and isolated severe weather. A historic flash flood occurred on the Blanco River late Saturday night into Sunday. Hundreds of homes were destroyed along the river from the City of Blanco down into Wimberley and San Marcos. The flood wave continued downstream for days affecting residents and homes along the San Marcos and Guadalupe Rivers. Early estimates show damages in excess of 100 million dollars. Several people lost their lives due to flash flooding. A large tornado outbreak occurred this Saturday night producing numerous small brief tornadoes.
